In a preview of the year ahead, Leavitt says the administration will work to limit the federal government's role in the delivery of health care. He said that goal puts it at odds with several Democratic proposals, such as giving the HHS secretary authority to negotiate drug prices and greatly increasing enrollment in government-sponsored health insurance for children.
